Description

one

 The invention relates to devices for processing plastics, to presses for injection molding.

Hydraulic presses with a mechanized table are known, which allow the die to be extended out of the forming zone in order to facilitate the loading of reinforcement and press material into it.

Also known is a press with a mechanized table, containing a punch attached to the press slide and a movable table with two dies alternately interacting with the punch.

However, due to the impact on the pressing forces of known presses, the substrates of the main table wear out quickly when pressing large-sized products.

The inventive principle is to exclude the effect of pressing force on the guides of the movable table.

The proposed press is distinguished by the fact that it is equipped with a spring-loaded frame mounted on a movable table for securing dies

Such an embodiment of the press ensures unloading of the guides of the rolling CTOJ; from the pressing force during the manufacture of large-sized products of the method of pressing on it.

The drawing shows the proposed press. "

The press consists of a bed 1 with stops 2, a movable table 3c with a frame 4 mounted on it, resting on springs 5. A plunger 6 is mounted on the press ram, and the matrix 4 and 8 are fixed on the frame 4.

The press works as follows. The matrix 7 is loaded with plasticized material, the press slider, op5 "is cut and the product is pressed, the frame 4 is lowered onto the stops 2, and the springs 5. Simultaneously, the matrix is cooled. At the end of the pressure shutter is produced. mooing the press and removing the product, while the springs 5 lift the frame 4 and a gap is formed between it and the stops 2.
